Subject: [PATCH] spi: Kill superfluous cast in spi_w8r16()
Date: Sun, 12 Jan 2014 13:59:06 +0100	[thread overview]
Message-ID: <1389531546-5867-1-git-send-email-geert@linux-m68k.org> (raw)

From: Geert Uytterhoeven <geert+renesas-Td1EMuHUCqxL1ZNQvxDV9g@public.gmane.org>

spi_write_then_read() takes a "void *" for rxbuf, so there's no need to
cast the buffer pointer to "u8 *".
